A/C compressor shutting off but

The A/C control has the choice of "on" or "auto" for the fan and we always keep it on "auto". I happened to hear the unit in the bedroom compressor cut off during the night last night, so I immediately turned the whole unit off as it is right by my side of the bed. We are hooked up at home right now so we didn't have both units running at the same time. I have not noticed it doing this before.

As far as we know these are the orginal units on this 2003 FW (we bought used) so they are 10 yrs old. They cool very well other than this happening last night.

You said it continues to run, 1 minute, 5 minutes, three hours? if I were designing an A/C the "Auto" mode might well not exist, but if it did the fan would delay shutting off by at least a minute.

That said.. I don't design them.

On many RV ACs the fan runs all the time while the AC compressor cycles on, and off. So is this a new thing for your AC? Is it keeping the TT cool?
If it has turned on, and off with the compressor in the past. It may be freezing up, In which case the TT would get warm inside. Or there may be a short in the controls.
